MINING-LOCOMOTIVE.

SPECIFICATION forming part of Letters Patent No. 794,867, dated July 18, 1905.

Application filed May 31, 1904. Serial No. 210,889.

To a whom, it may concern Be it known that I, AUGUSTUS H. Kons- MEYER, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Mining-Locomotives, of which the following is a specification.

This invention relates to locomotives for use in mines where space is limited and light and pure air are desirable to permit the mining operations to be prosecuted with celerity and safety. I

My object therefore is to produce a locomotive of small and compact-construction and practically smokeless in operation.

l/Vith this general object in view theinvention consists in certain novel and peculiar features of construction and combinations of parts as hereinafter described and claimed, and in order that it may be fully understood reference is to be had to the accompanying drawings, in which Figure 1 is a central vertical longitudinal section of a locomotive embodying my invention, the water-tank being shown in elevation. Fig. 2 is a section taken on the line II II of Fig. 1. Fig. 3 is a rear elevation of the locomotive.

In the said drawings, 1 designates the frame, mounted upon axles 3 and 4, equipped with traction-wheels 5 and 6 for travel on a suitable trackway, as at 7. I

The boiler consists of the cylindrical body portion 8, communicating atits front and rear ends, respectively, with the manifold-chambers 9 and 10, said chambers being also. connected by a series of tubes 12, which are pitched or inclined downwardly and forwardly.

Arranged vertically below water-tubes 12 are hydrocarbon-burners 13, the same being preferably of disk form and provided with a plurality of nipples 14 and connected to the supply-pipes 15 in any suitable manner, said supply-pipes extending to a point beyond the rear end of the boiler and to a gasolene tank 16, supported in any suitable manner, and said supply-pipes are equipped with valves 17 to control the flow of the gasolene to the burners.

The boiler is arranged within a housing or casing consisting of an inner shell 18 and an outer shell 19, disposed a suitable distance apart to provide an air-space 24 between them. The inner shell is provided with heads 20 21 and the outer shell with heads 22 23, suitably spaced so as-to provide the air-chambers 25 and 26. The various air-chambers mentioned being poor conductors, but little radiation of heat from the outer shell occurs, which not only results in a quicker generation of steam and greater economy of fuel, but 'also eliminates danger of injury to any one who might come in contact with the housing, it being understood, of course, that tunnels in coalmines are frequently so narrow that it would be impossible .for one to pass a locomotive without touching it. The bottom of the housing is in the form of a plate 27, provided with apertures 28 for the admission of air to support combustion.

29 designates a series of short flues connecting and extending through the shells of the housing above the boiler,and 30 is a slideplate mounted externally of the outer shell and guided in position by suitable lugs 31 thereon. The slide-plate is pivotally connected by a link 33, witha lever 32 fulcrumed on bracket 34, secured to the housing. By means of this lever the slide-plate is moved to cause its row of apertures 36 to move into or out of registration with said flues, the force of the draft through the flues being increased or diminished by the complete or partial registration of said apertures with said flues.

37 designates a pair of steam-cylinders disposed below the rear end of the housing and having their steam-chests 38 at their outer sides, and leading from said chests are pipes 39, which are connected to a pipe 40, communicating with the upper part of manifoldchamber 10, and mounted on said steam-supply pipe 40 is a throttle-valve 41, to be opened or closed through the agency of lever 42, mounted on the housing. The piston-rod of each cylinder is connected, through the medium of a cross-head 44, with a driving-rod 43, mounted at its front end on the wrist-pin of a gear-pinion 46, journaled on a stubshaft 47, suitably supported from the framework, and said pinion meshes with a gearwheel 48, keyed or otherwise rigidly secured on axle 3. Traction-wheels 5 are pivotally connected by a driving-rod 4:9 and tractionwheels 6 by a similar driving-rod 50, said rods being set quartering in the usual manner.

The boiler is supplied with water in the usual or any preferred manner from watertank 51, and access is had to the burners, the under side of the boiler, the driving-gearing, and the engine-cylinders by removing door 52, which is held in place normally by lugs 53 and a pivoted latch or turn-button 54. Upon the rear end of the platform are boxes 56 for holding tools, &c.

Assuming that the boiler is charged with the requisite volume of water and tank 16 with a suitable supply of gasolene, the engineer when ready to generate steammanipulates lever 32 to dispose the perforations of plate 30 in line with tubes 29 and then opens valve 17 and in any suitable manner starts the burners in operation. Immediately thereafter the heat generated establishes and gradually increases the circulation of air up through perforations 28 to support combustion, and this hot air threads its way upwardly and between the tubes 12 against the bottom of the body of the boiler and passes upwardly at opposite sides of the latter and escapes through fiues 29 and apertures 36. After the burners have been in operation a suflicient length of time to generate and raise the steam to the required pressure the throttle-valve is opened to permit the steam to enter the cylinders and through the gearing described effect the propulsion of the locomotive, it being understood, of course, that after the steam has been raised to the required pressure the valve 17 may be partially closed and still generate sufficient heat for the proper operation of the 10- comotive, this operation taking place under a substantially perfect combustion, and consequently being attended by the production of but little, if any, smoke.

The locomotive is started and stopped by the usual manipulation of the throttle-valve, though of course the equipment may also in- 'clude a system of brakes. (Not shown, because forming no part of the present invention.)

From the above. description it will be apparent that I have produced a mining-locomotive possessing the features of advantage enumerated as desirable in the statement of invention and which may obviously be modified in minor particulars without departing from the spirit and scope of the appended claims.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a mining-locomotive, the combination of a wheeled frame, a housing thereon, consisting of an inner and an outer shell, a perforated bottom common to both shells, one or more flues connecting and extending through the upper part of the shells, a boiler in the inner shell vertically below said flues, burners within the inner shell and below the boiler, and a valve for controlling the passage of said flue or flues.

2. In a mining-locomotive, the combination of a wheeled frame, a housing thereon, consisting of an inner and an outer shell, a perforated bottom common to both shells, one or more flues connecting and extending through the upper part of the shells, a boiler in the inner shell vertically below said flues, burners within the inner shell and below the boiler, an oil-supply tank, valve controlled pipes connecting the tank with the burners, and a valve for controlling the passage of said flue or fines.

3. In amining-locomotive, a wheeled frame, a housing thereon consisting of an inner and an outer shell having a dead-air space between them, a perforated bottom common to both shells, a longitudinal series of vertical flues connecting and extending through the upper part of the shells and bridging the dead-air space, a perforated slide valve or plate mounted on the upper side of the outer shell above said fiues to control the passages thereof, and burners within the inner shell above the perforated bottom thereof and vertically below said series of flues.

In testimony whereof I afiix my signature in the presence of two witnesses.

AUGUSTUS H. KORSMEYER.
